MounLin l'or Botvle flashe Brushes, of wh c iollomng is 1;. iii 1, clear, and exact Mon.

My invention relates to bottle washer brushes, my more particular purpose being to improve the mountings for such brushes.

llcl'erence to be had to the accoinpan ing drawings forming part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is fragmentary section showing my iinprored device in (accretion; Fig. 2 is a horizontal section upon the line 2-2 of Fig. l, looking in the direction of the erroug'and showing the pivotal mountings for the brush arms carrying the flexible brushes upon the ferrule; 8 is a vertical section upon the line 3-3 or l, looking in the direction of the arrow, and showing the brush arms, the brushes and spring" mechanism connected with the brushes lor causing the same to open; and Fig. 4 is aview pcrtl in plan and partly in section, showing one of the brush arms carrying its brush.

- A bottle to be washed is shown at 5.

At 6 is a tubular spindle. which carries a ferrule '7 secured rigidly thereupon. This ferrule is provided with S which sup port a pivot pin 9 extending from one of the ears 8 directly across to the other. Mounted ed with the latter is a spiral spring 11. Journaled upon the pivot pin 9 are brush arms 12, each being provided with clamping plates 13 between which is the brush 15. The clanning plates are connected by a screw 14 .t 1e pressure of which causes them to approach each other and thus bind upon opposite sides of the brush. This brush is made of rubber and is reinforced with canvas 16, as will be understood from F l. Each brush 15 is provided with a substantially cylindrical portion 17, and each brush arm 12 is provided with a slot 18, the general form of which is substantially cylindrical. Thecylindrical portion 17 of the brush fits neatly into the slot 18 of the brush arm, and may be inserted in position by merely pushing the brush into the brush arm, that is,-

in practice tirecylindrical portion 37 of the brush is first pushed into the slot 18 0f the brush arm, the clamping; plates l3 being sprung slightly apart in order to permit the ready insertion of the body portion of the brush. The screw 14 is next placed position and causes the clamping plates to grip tightly upon opposite sides of the. brush.

Each brush arm 12 is provided with a slot 19, and with a main pivot hole 20 and a smaller pivot hole 21. The pivot 9 extends through the pivot holes 20 of the brush. Each pivot hole 21 is fitted with a smaller pivot 22, and connecting the two pivots ol' the two brush-s is a bail 23. The two balls are connected together by a hook 24; at the end of spring 11, which extends through eyes 26 carried by the bails, and also through a spacing block having the form. oii'a roller, as indicated in Fig. 3. .The tension of the spring 11, by pulling upon the bails 23, and consequently upon the pivots 22, gives the arms 12 a tendency to spring out, as iudicated in Fig. 1, so that the brushes brought into engagement with the interior of the bottle 5. This movement occurs when ever the device is inserted Within the bottle. In order to do this, the brushes are rocked upon the pivots 9 so that the outer ehds ol the brushes ap roach each other, and with the brushes an brush arms in this position, they are inserted through the neck of the bot-- tle. Once inside they spring outwardly and engage the interior of the bottle, as indicatedin Fig. 1. tucked in the usual manner, and water being caused to flow through the spindle 6, the interior of the bottle is effectively Washed. This operation being completed, the withdrawal of the device from the bottle causes the brushes to be forced toward each other for an instant, they spring backward into normal 'osition immediately afterward.

It wil be noted that the brush arms 12 are slightly cut away at the point 12, as indicated in Fig. 1. This is for the purpose of facilitating the entrance of the brushes into the brush arms and also to enable the operator to guide the cylindrical portion 17 of the brush into the slot This he, does by grasping the arm at any convenient point adjacent to the cylindrical portion 17 and The brushes being'now ac-- steadying this portion as it is pushed into the slot 18. I The brush arms 12 are unable to -bend backward to any appreciable extent,

for the reason that, being journaled upon the pivot 9 and encountering the body portion of the ferrule 7, their movement backward is thus limited. The net result is that the brushes normally stand straight out from the axis of the ferrule, as a center, and can 1 not be bent from this direction except as above described. The bail 23 being of spring metal permits the ivots 22 upon the two arms to move slight y toward and from each other in order to accommodate the swinging movement of the arms.

Having thus described my invention, 1'

claim as new and desire to secure by Letters Patent:

1. The combination of a ferrule, brush arms journaled thereupon, a s ring connected with said ferrule, and a bai connected with. said brush arms and with said spring.

2. The a combination of a ferrule provided with ears, a ivot extending from one of said ears to anot er, brush arms journaled upon said pivot and adapted to rock, said brush arms being so ositioned as to engage portions of said. ferru. e, thereby limiting the travel of said arms, and mechanism connected with said arms for moving the same upon said pivot.

The combination of a brush arm provided with a slot, and with clamping plates, a rush provided with portions disposed intermediate said clamv ing plates, said brush be- 5. The combination of a ferrule, brush arms journaled thereupon, a spring for actuating said brush arms, a spacing member mounted upon said spring, and bails disposed upon opposite sides of said spacing.

7. The combination of a ferrule, a pairof brush arms journaled thereupon, a tensile spring, a connection from said tensile spring to both of said brush arms for the purpose of moving said brush arms in opposite direc, tions.

8. The combination of a ferrule, brush arms journaled thereupon and adapted to swing outwardly, a single tensile sprin for actuatin both of said brush arms and a bail, j ournale to both of said brush arms and connected with said tensile spring for the purpose of actuating said brush arms.

9. The combination of a ferrule, brush arms journaled thereupon and adapted to swin outwardly, said brush arms belng provide with'slots, fastenin members mounted within said slots, a tensi e spring supported by said ferrule, and connections from said tensile spring to, said fastening members within said slots.

In testimony whereof I have signed'my name to this specificationin the presence of two subscribing witnesses.
